#$%^&*AU2020203656A120200702.pdf#####213/913PCT Abstract A cannula system and method for accessing a blood mass in the brain. The system comprises a cannula with a camera mounted on the proximal end of the cannula with a view into the cannula lumen and the surgical field below the lumen. A prism, reflector or other suitable optical element is oriented between the camera and the lumen of the cannula to afford the camera a view into the cannula while minimizing obstruction of the lumen. The system may also include an obturator with a small diameter shaft and a large diameter tip which is optically transmissive, so that a surgeon inserting or manipulating the assembly can easily see that the obturator tip is near brain tissue (which is white) or blood (which is red). 55212/213PCT 2/9 5 12 Fi. 75 21 21 1 4 12 Ii <； 21Fi .172 21b. - -- ---5 1 1 --- --- -- --- ---- ---- --½ 9 . 20
